Is ellipse a simple arc?
An ellipse has a simple algebraic solution for its area, but only approximations for its perimeter (also known as circumference), for which integration is required to obtain an exact solution. Ellipses are the closed type of conic section: a plane curve tracing the intersection of a cone with a plane (see figure).

How do I convert an arc to a polyline in AutoCAD?
You can convert lines, arcs or even splines to a polyline curve using the Polyline Edit command.
